Hybrid temporary anchorage device implant system and associated methods

Abstract

A hybrid temporary anchorage device implant system and method of use is disclosed. A temporary anchorage device (TAD) implant includes an external hex head, a cupped inner portion, a threaded core, a platform, and an implant portion. A first abutment is installed on the implant portion. The first abutment may include a graduated portion, a screw-retained healing collar, and a threaded portion. A second abutment may be installed over the first abutment. The second abutment may include a graduated head, a bulbous base, and an inner canal.

I claim: 
     
       1. A system comprising:
 a temporary anchorage device (TAD) implant, the TAD implant comprising:
 an implant portion; 
 a platform disposed on one end of the implant portion; and 
 a hexagonally-shaped head disposed on the platform, the hexagonally-shaped head having an interior comprising a cupped inner portion and a threaded core depending from the cupped inner portion, the threaded core having female threads for accepting a threaded portion of a first abutment the system further comprising a second abutment, the second abutment comprising: a graduated portion having a first end and a second end, a bulbous base disposed at the first end of the graduated portion of the second abutment, an inner canal expanding through the graduated portion of the second abutment and the bulbous base, the inner canal having a female hex, a first elevation extending partially around a circumference of an outer wall of the second abutment, a second elevation extending from a widest circumference of the bulbous base to the second end of the graduated portion; wherein the second abutment is affixed to the TAD implant such that the bulbous base is disposed on the hexagonally-shaped head, and the threaded portion of the first abutment traverses an interior of the second abutment and is coupled to the threaded core of the hexagonally-shaped head. 
 
 
     
     
       2. The system of  claim 1 , further comprising a first abutment, the first abutment comprising:
 a graduated portion, and 
 a threaded portion connected to the graduated portion of the first abutment at a junction. 
 
     
     
       3. The system of  claim 1 , wherein the implant portion comprises self-tapping threads thereon. 
     
     
       4. The system of  claim 1 , wherein the hexagonally-shaped head has a length of 2 millimeters. 
     
     
       5. The system of  claim 1 , wherein the implant portion is comprised of titanium. 
     
     
       6. The system of  claim 1 , wherein the implant portion is comprised of stainless steel. 
     
     
       7. The system of  claim 1 , wherein the platform has a length of 0.5 millimeters. 
     
     
       8. The system of  claim 1 , wherein the implant portion descends from the hexagonally-shaped head at a taper angle. 
     
     
       9. The system of  claim 1 , wherein the abutment is comprised of titanium without a treatment with a chemical or biological coating. 
     
     
       10. The system of  claim 2 , wherein the graduated portion comprises a plurality of grooves that span a circumference of an outer portion of an exterior surface of the graduated portion. 
     
     
       11. The system of  claim 1 , wherein the second abutment is comprised of a radiopaque plastic. 
     
     
       12. The system of  claim 1 , wherein the second abutment is comprised of polyetheretherketone. 
     
     
       13. The system of  claim 1 , wherein the second abutment has a length ranging from 3 millimeters to 6 millimeters. 
     
     
       14. The system of  claim 1  wherein the second abutment comprises a plurality of grooves formed on the graduated portion of the second abutment. 
     
     
       15. The system of  claim 1 , wherein the second elevation has a width of 1 millimeter. 
     
     
       16. The system of  claim 2 , wherein the first abutment is comprised of stainless steel.
